We read with interest the paper on "susceptibility-weighted imaging: The value in cerebral astrocytomas grading" by Zhang and colleagues. [1] The authors have concluded that "CE-SWI was better than CE-T1WI in visualizing tumor architecture. There are some concerns on this study; the study sample is small and there was no assessment of the effect of image interpreter' experience. In fact, it is necessary to differentiate the astrocytoma from other highly similar lesions in CE-SWI such as lymphoma, [2] brain abscess [3] and others. In other similar study, it has been observed that the diagnostic accuracy of CE-SWI was not good and the sensitivity and specificity were 81.8% and 80.0%, respectively. [4]
